Well, if the idea's to eventually remove the old order, or let it
expire as it becomes hard to support, it's better if it's a tag to
support the old order.

Another option would be to add it as an element of the BMP drawing tag
itself? The current way BMPs are drawn would mean "I don't care about
the order" and with the presence of the additional bit, it would mean
"draw it now."
